Lancer had a similar problem with an engine built by a reputable shop using similar techniques and products. The rings took a long time to seat as I recall.
Don't use synthetic oil to break in the engine. Use the dinosaur stuff.
I would say two things you could try. My first examination would be to get the engine hot, let it cool down to the point you can pull the plugs, and run a compression leak down test. At the same time read the plugs and see if you think there is anything odd about one plug or all.
No matter what you find, another test is to find a way to disable the turbo, and block off the oil. That's a little radical, but it eliminates the possible oil entry to the combustion. You don't have to drive it too hard to find out if the turbo is part of the problem, but you really won't know until you're sure the rings are seated.
And it might be both -- rings not seating, and the turbo.
In any case, doing a leak down compression test is where you need to start to figure out if the rings are sealing or not.
I recall Lancer put in a hotter thermostat to build more heat in the engine so to help the rings to seat. Wouldn't it be wonderful, if all it took was a hotter thermostat......
Off the subject, the tool for ASCO Canada came yesterday....testing it on the #6 rib today, so that will tell us if our trip to the Northwest is happening sooner than later. We may have a posse to come up right after Easter, and drool into your intake manifold with some good 'ol Ameereekan spit. That should seal the rings for good.
I have an article that addresses oil consumption in aircraft engines that is very interesting, so I'll try to find it and email it to you.
AND, just another thing to check is to make sure you have the right oil dipstick matched to the gearbox. My guess is you measured oil to the milliliter for what to put in the engine. We had engine oil problems ( leaking, etc ) when mating a late model transmission and used the early model dipstick ( or the wrong one if you will ) and so there was an excessive amount of oil in the sump. Just another thing to check out in case you mixed and matched up a different gearbox as I can't recall.
